The innovative addi Rocket2 [Squared] are an amazing new concept in knitting needles, combining ease of needle handling with built-in stitch support! The addi Rocket² [squared] line of square shaped circular needles has the same speedy addi Turbo finish and features the beloved addi Rocket tapered tips. The needle shaft shape is a gently rounded square to provide easy grip with more relaxed handling. The spiraling surface makes for excellent slip along the needle shaft, while at the same time stabilizing the slide of the stitches along the length. This new ergonomic design may alleviate the frustration that comes when a knitter is able to reduce the pain or strain while knitting. Available in lengths (measured from tip to tip): 16-inch, 20-inch, 24-inch, 32-inch, 40-inch, 47-inch, and 60-inch. Needle sizes US 1 (2.5 mm) to US 11 8.00 (mm), including US 10.5 (6.50 mm) and US 10.75 (7.00 mm).
